# Register Domain

Registers a domain with Apple Pay.

This endpoint allows you to register your website domain with Apple Pay, which is required before you can accept Apple Pay payments on your website. The domain must be accessible via HTTPS and have a valid SSL certificate.

Before registering, you must download this [domain association file](https://assets.monei.com/apple-pay/apple-developer-merchantid-domain-association/) and host it at `/.well-known/apple-developer-merchantid-domain-association` on your site.

For example, if you're registering `example.com`, make that file available at `https://example.com/.well-known/apple-developer-merchantid-domain-association`.

The file has no extension, which trips up some servers (notably IIS, and any setup that strips or rejects extensionless static files). Make sure the URL returns HTTP 200 with the file's raw contents — not a 404, redirect, or HTML page. Serving it as `Content-Type: text/plain` is the safest choice; add an explicit MIME mapping for the extensionless filename if your server needs one.

After registration, Apple will verify your domain. Once verified, you can display Apple Pay buttons and process Apple Pay payments on your website.
